3V Active Buzzer 10mm Through Hole Electronic Piezo Buzzer for Arduino ESP32

3V Active Buzzer – 10mm Through Hole Electronic Piezo Buzzer

The 3V Active Piezo Buzzer is a self-driven audio component that generates a fixed-frequency tone when powered — no external oscillator or PWM signal required. At just 10mm in diameter, it fits neatly on breadboards and PCBs, making it the go-to choice for audio feedback in embedded systems and IoT devices.

Key Specifications

• Type: Active (self-oscillating)
• Operating Voltage: 3V DC (compatible with 3.3V logic)
• Diameter: 10mm
• Mounting: Through-hole, 2-pin
• Frequency: ~2.3 kHz (fixed)
• Sound Output: ≥85 dB at 10cm
• Current Consumption: ≤30 mA

Compatibility & Use Cases

This buzzer works directly with Arduino, ESP32, Raspberry Pi Pico, and other 3.3V/5V microcontrollers (use a transistor for 5V boards). Common applications include:

• Alarm and alert systems in IoT sensor nodes
• Doorbell and notification circuits
• Countdown timers and event triggers
• Robotics collision or boundary alerts
• STEM kits and beginner electronics projects

Simply connect VCC and GND — the buzzer activates immediately, making it ideal for quick prototyping without complex code.
